Because one of our classes become too big with nearly 100 properties,
we must split it to 5 smaller classes (and inturn, 5 different tables)
to save performance. But now if I wanna access the base object from
part object, it is null. Here is the code:
namespace beans
{
public class City
{
public CityResourcesData Resources
{
get;
set;
}
public SomeEntity SomeProperty
{
}
}
public class CityResourcesData
{
private int _wood, _clay, _iron;
#region Properties.Resources
public virtual int Wood
{
get { return this._wood; }
set
{
int max = this.Village.MaxResources;
if (value > max)
this._wood = max;
else if (value < 0)
this._wood = 0;
else
this._wood = value;
}
}
public virtual int Clay
{
get { return this._clay; }
set
{
int max = this.Village.MaxResources;
if (value > max)
this._clay = max;
else if (value < 0)
this._clay = 0;
else
this._clay = value;
}
}
public virtual int Iron
{
get { return this._iron; }
set
{
int max = this.Village.MaxResources;
if (value > max)
this._iron = max;
else if (value < 0)
this._iron = 0;
else
this._iron = value;
}
}
#endregion
public virtual City City
{
get;
set;
}
}
}
and the mapping:
<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class name ="beans.City, beans" table="city_common" lazy="false">
<id name="ID" column="id" type="Int32">
<generator class="identity"/>
</id>
<property name="SomeProperty" column="some_column"/>
<many-to-one name="Resources" class="beans.CityResourcesData,
beans" column="id" fetch="select" lazy="proxy" />
</class>
<class name ="beans.CityResourcesData, beans" table="city_resources"
lazy="true">
<id name="ID" column="id" type="Int32">
<generator class="foreign">
<param name="property">City</param>
</generator>
</id>
<property name="Gold" column="gold" />
<one-to-one name="City" class="beans.City, beans"
constrained="true"/>
</class>
Please help!!!
